BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a casing assembly and, more particularly, to a casing assembly for accommodating a stylus.

Description of the Prior Art

With the progress and development of technology, tablet computers are commonly used by people in the daily lives or for work. In general, a tablet computer may be used selectively with a stylus to perform operations such as writing, manipulating and drawing.

A current common tablet computer is provided with an accommodation recess for placing a stylus. When the stylus is not in use, the stylus may be stored in the accommodation recess and be prevented from being lost. In order to prevent the stylus stored from unexpectedly disengaging from the accommodation recess, the stylus is secured in the accommodation recess by a fixing means, and a user needs to pick the stylus by a finger in order to get the stylus out of the accommodation recess. However, if the stylus is secured too tightly in the accommodation recess, it may be difficult for the user to pick the stylus out of the accommodation recess. More particularly, when a user wears gloves, picking the stylus out of the accommodation recess by a finger may become even more difficult under the influence of the thickness of the gloves. Therefore, manufacturers of tablet computers are dedicated to improving such issue.

SUMMARY OF THE INVENTION

The present invention provides a casing assembly that allows a stylus to be easily taken out of an accommodation recess.

A casing assembly for accommodating a stylus is disclosed by an embodiment of the present invention. The casing assembly includes a casing and a button. The casing has an accommodation recess and an opening in communication with each other. The accommodation recess has a first end and a second end opposite to each other on a longitudinal axis thereof, and accommodates the stylus. The opening extends from the first end to the second end. The button includes an operation portion and a pushing portion connected to each other. The operation portion is pivotally disposed at the casing so as to be pivotable between an initial position and a released position. The pushing portion is located in the accommodation recess. When the operation portion is pivoted from the initial position to the released position, the pushing portion in the accommodation recess is moved toward the opening so as to push the stylus out of the accommodation recess.

A casing assembly for accommodating a stylus is further disclosed by another embodiment of the present invention. The casing assembly includes a casing and a button. The casing has a groove. The button is movably disposed in the groove of the casing so as to be movable between an initial position and a released position. The button has a pushing portion, and an accommodation recess and an opening that are in communication with each other. The accommodation recess has a first end and a second end opposite to each other on a longitudinal axis thereof, and accommodates the stylus. The opening extends from the first end to the second end. When the button moves from the initial position to the released position, the pushing portion approaches the opening from the accommodation recess so as to push the stylus out of the accommodation recess.

According to the casing assembly disclosed by the embodiments above, the pushing portion of the button is enabled to push the stylus out of the accommodation recess by operating the operation portion of the button. Thus, compared to a conventional approach of picking a stylus by a finger, the design of operating the button to withdraw the stylus from the accommodation recess provides a more convenient stylus pick-up operation. In particular, even when a user wears gloves, the user is still able to easily press the button to push the stylus out of the accommodation recess and then directly take the stylus.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Refer to FIG. 1 to FIG. 3 . FIG. 1 shows a three-dimensional schematic diagram of a casing assembly and a stylus disclosed according to a first embodiment of the present invention. FIG. 2 is an exploded schematic diagram of FIG. 1 . FIG. 3 is a cross-sectional schematic diagram of FIG. 1 .

In this embodiment, a casing assembly 1 a is for accommodating a stylus 2. The casing assembly 1 a includes a casing 10 a and a button 20 a. Moreover, the casing assembly 1 a may further include a magnetic member 30 a and two elastic members 40 a.

The casing assembly 1 a is, for example, a casing of an electronic device. The casing 10 a is, for example but not limited to, a backplate of a tablet computer. The casing 10 a has an outer surface 11 a, an accommodation recess 12 a and an opening 13 a. The accommodation recess 12 a is formed as being recessed from the outer surface 11 a, and has a first end 121 a and a second end 122 a opposite to each other. The first end 121 a and the second end 122 a are respectively located on two opposite sides on a longitudinal axis P1 of the accommodation recess 12 a. A plane where the opening 13 a is located is, for example, coplanar with the outer surface 11 a of the casing 10 a, and the opening 13 a extends from the first end 121 a to the second end 122 a of the accommodation recess 12 a. The accommodation recess 12 a is for accommodating the stylus 2.

In this embodiment, the plane where the opening 13 a is located is not limited to being coplanar with the outer surface 11 a of the casing 10 a. In another embodiment, the plane where the opening is located may be non-coplanar with the outer surface of the casing, and may be, for example, higher than the outer surface of the casing.

The magnetic member 30 a is, for example, embedded in the casing 10 a, and is near the accommodation recess 12 a. The magnetic member 30 a is for magnetically attracting another magnetic member 3 disposed in the stylus 2, and hence magnetically fixes the stylus 2 in the accommodation recess 12 a. The magnetic member 30 a is not limited to being embedded in the casing 10 a. In another embodiment, the magnetic member may be exposed from an inner wall surface of the accommodation recess. In yet another embodiment, the magnetic member may be omitted from the casing assembly.

In this embodiment, the casing 10 a may further include a button slot 14 a. The button slot 14 a is formed as being recessed from an inner wall surface 123 a of the accommodation recess 12 a, and is located between the first end 121 a and the second end 122 a of the accommodation recess 12 a. The button 20 a includes an operation portion 21 a, a pushing portion 22 a and a stopping portion 23 a. The pushing portion 22 a and the stopping portion 23 a are connected to two opposite sides of the operation portion 21 a, respectively, and the operation portion 21 a, the pushing portion 22 a and the stopping portion 23 a jointly form a groove 24 a. The groove 24 a is for collaborating with the accommodation recess 12 a to accommodate the stylus 2. The operation portion 21 a is in part located in the button slot 14 a and the operation portion 21 a is pivotally disposed at the casing 10 a, and the pushing portion 22 a is located in the accommodation recess 12 a.

In this embodiment, the operation portion 21 a is adapted to be pivotable between an initial position A1 (as shown in FIG. 3 ) and a released position A2 (as shown in FIG. 4 ). The two elastic members 40 a are, for example, torsion springs. On of the elastic members 40 a is disposed between one side of the operation portion 21 a of the button 20 a and the casing 10 a, and the other elastic member 40 a is disposed between the other side of the operation portion 21 a of the button 20 a and the casing 10 a. The two elastic members 40 a are for applying a force for pivoting the operation portion 21 a from the released position A2 to the initial position A1.

As shown in FIG. 3 , when the stylus 2 is accommodated in the accommodation recess 12 a and the groove 24 a and the operation portion 21 a of the button 20 a is located at the initial position A1, the pushing portion 22 a is located on one side of the accommodation recess 12 a away from the opening 13 a, and the stopping portion 23 a is located at the opening 13 a and extends to be diagonally above the accommodation recess 12 a, so as to limit the stylus 2 within the accommodation recess 12 a.

Next, refer to FIG. 4 . FIG. 4 shows a cross-sectional schematic diagram of the stylus in FIG. 3 disengaged from the accommodation recess.

As shown in FIG. 4 , to take the stylus 2 out of the accommodation recess 12 a, the operation portion 21 a of the button 20 a may be pressed by a finger, so that the operation portion 21 a is pivoted from the initial position A1 to the released position A2. During the process of the operation portion 21 a moving from the initial position A1 to the released position A2, the operation portion 21 a causes the elastic members 40 a to store an elastic restoring force, the stopping portion 23 a is away from the opening 13 a, and the pushing portion 22 a moves from one side of the accommodation recess 12 a away from the opening 13 a toward the opening 13 a. As such, the thrust of the pushing portion 22 a of the button 20 a overcomes the magnetic attraction force between the two magnetic members 30 a and 3, and then pushes the stylus 2 (located in the accommodation recess 12 a) out of the accommodation recess 12 a, allowing the stylus 2 to be taken directly. Once the finger moves away from the button 20 a, the elastic force of the elastic members 40 a causes the operation portion 21 a of the button 20 a to return from the released position A2 to the initial position A1.

In this embodiment, the pushing portion 22 a of the button 20 a is enabled to push the stylus 2 out of the accommodation recess 12 a by pressing the operation portion 21 a of the button 20 a. Thus, compared to a conventional approach of picking the stylus 2 by a finger, the design of operating the button 20 a to withdraw the stylus 2 from the accommodation recess 12 a provides a more convenient stylus pick-up operation. In particular, even when a user wears gloves, the user is still able to easily press the button 20 a to push the stylus 2 out of the accommodation recess 12 a and then directly take the stylus 2.

Moreover, the stylus 2 is pushed out of the accommodation recess 12 a by the pushing portion 22 a of the button 20 a, in a direction substantially perpendicular to the longitudinal axis P1 of the accommodation recess 12 a, but not in a direction of the longitudinal axis P1 of the accommodation recess 12 a. Thus, it is not necessary for the accommodation recess 12 a of the casing 10 a to extend to the edge of the casing 10 a, hence minimizing the influence of a reduced internal space of the casing 10 a caused by the accommodation recess 12 a provided and further benefiting the utilization of the internal space of the casing 10 a.

Next, to place the stylus 2 back to the accommodation recess 12 a, in a state where the operation portion 21 a of the button 20 a is at the released position A2, the stylus 2 is first placed in the groove 24 a, and the stylus 2 is brought back to the accommodation recess 12 a by the button 20 a, while the operation portion 21 a of the button 20 a is pivoted back to the initial position A1 by the elastic force of the elastic members 40 a. Alternatively, in a state where the operation portion 21 a of the button 20 a is at the initial position A1, the stylus 2 is directly fitted into the accommodation recess 12 a and the groove 24 a.

In this embodiment, when the button 20 a is not pressed, the stylus 2 in the accommodation recess 12 a is limited by the stopping portion 23 a. Thus, even if the casing 10 a receives an unexpected external impact (such as falling onto the ground), it is ensured that the stylus 2 does not disengage from the accommodation recess 12 a.

In this embodiment, the number of the elastic members 40 a is not limited to being two. In another embodiment, the casing assembly may include only one elastic member. In another embodiment, the elastic member may be omitted from the casing assembly. In such configuration, the button may be kept at the initial position by an appropriate structure or element when no external force is exerted thereon.

Next, refer to FIG. 5 to FIG. 7 . FIG. 5 shows a three-dimensional schematic diagram of a casing assembly and a stylus disclosed according to a second embodiment of the present invention. FIG. 6 shows an exploded schematic diagram of FIG. 5 . FIG. 7 shows a cross-sectional schematic diagram of FIG. 5 .

In this embodiment, a casing assembly 1 b is for accommodating a stylus 2. The casing assembly 1 b includes a casing 10 b and a button 20 b. Moreover, the casing assembly 1 b may further include two elastic members 41 b and 42 b.

The casing 10 b is, for example, a backplate of a tablet computer. The casing 10 b has a receiving slot 11 b. The receiving slot 11 b has, for example, a first receiving portion 111 b and two second receiving portions 112 b. The first receiving portion 111 b is located between the two second receiving portions 112 b, and is in communication with the two second receiving portions 112 b. A length L1 of the first receiving portion 111 b is greater than a length L2 of the two second receiving portions 112 b.

The button 20 b is movably disposed in the receiving slot 11 b of the casing 10 b. More specifically, the button 20 b has an accommodation recess 21 b, an arc inner wall surface 22 b, an opening 23 b, a through hole 24 b and a pushing portion 25 b. The accommodation recess 21 b is formed by the arc inner wall surface 22 b, and has a first end 211 b and a second end 212 b opposite to each other on a longitudinal axis P2 of the accommodation recess 21 b. The opening 23 b and the through hole 24 b are located on two opposite sides of the accommodation recess 21 b and are both in communication with the accommodation recess 21 b, and the opening 23 b extends from the first end 211 b to the second end 212 b. The accommodation recess 21 b is for accommodating the stylus 2. The first receiving portion 111 b of the receiving slot 11 b has a slot opening 1111 b and a slot bottom surface 1112 b, wherein the slot bottom surface 1112 b faces the slot opening 1111 b. The pushing portion 25 b is, for example, a column, and the pushing portion 25 b is connected to the slot bottom surface 1112 b of the first receiving portion 111 b and is insertedly disposed in the through hole 24 b.

Further, the button 20 b includes a receiving portion 26 b, a first stopping portion 27 b, a second stopping portion 28 b, a first operation portion 29 b and a second operation portion 30 b. The first stopping portion 27 b and the first operation portion 29 b are connected to one side of the receiving portion 26 b, and extend toward different directions, respectively. The second stopping portion 28 b and the second operation portion 30 b are connected to the other side of the receiving portion 26 b, and extend toward different directions, respectively. Different portions of the arc inner wall surface 22 b forming the accommodation recess 21 b are located at the receiving portion 26 b, the first stopping portion 27 b and the second stopping portion 28 b, respectively. That is to say, the accommodation recess 21 b is jointly formed by the receiving portion 26 b, the first stopping portion 27 b and the second stopping portion 28 b. The receiving portion 26 b is located at the first receiving portion 111 b of the receiving slot 11 b, and the first operation portion 29 b and the second operation portion 30 b are located at the two second receiving portions 112 b of the receiving slot 11 b, respectively.

In this embodiment, the button 20 b is adapted to be movable between an initial position B1 (as shown in FIG. 7 ) and a released position B2 (as shown in FIG. 8 ) relative to the casing 10 b. The two elastic members 41 b and 42 b are, for example, compression springs. The two elastic members 41 b and 42 b are located at the two second receiving portions 112 b of the receiving slot 11 b, respectively, two opposite ends of the elastic member 41 b are connected to the first operation portion 29 b of the button 20 b and the casing 10 b, respectively, and two opposite ends of the elastic member 42 b are connected to the second operation portion 30 b of the button 20 b and the casing 10 b, respectively. The two elastic members 41 b and 42 b are for applying a force for moving the button 20 b from the released position B2 to the initial position B1.

As shown in FIG. 7 , when the button 20 b is located at the initial position B1 and the stylus 2 is accommodated in the accommodation recess 21 b, the stylus 2 is limited by the first stopping portion 27 b and the second stopping portion 28 b and is hence fixed in the accommodation recess 21 b. At this time point, the pushing portion 25 b of the button 20 b is, for example, slightly protruding from the arc inner wall surface 22 b of the button 20 b, and is located on one side of the accommodation recess 21 b away from the opening 23 b.

Next, refer to FIG. 8 . FIG. 8 shows a cross-sectional schematic diagram of the stylus in FIG. 7 disengaged from the accommodation recess.

To take the stylus 2 out of the accommodation recess 21 b, the first operation portion 29 b and the second operation portion 30 b of the button 20 b may be pressed by two fingers, such that the button 20 b moves from the initial position B1 to the released position B2. During the process of the button 20 b moving from the initial position B1 to the released position B2, the receiving portion 26 b of the button 20 b moves toward the slot bottom surface 1112 b of the first receiving portion 111 b of the casing 10 b, such that the pushing portion 25 b protrudes even more from the arc inner wall surface 22 b and approaches the opening 23 b of the button 20 b along a radial direction of the arc inner wall surface 22 b, and overcomes the limitation posed by the first stopping portion 27 b and the second stopping portion 28 b so further push the stylus 2 out of the accommodation recess 21 b. When the fingers move away from the button 20 b, the elastic force of the elastic members 41 b and 42 b causes the button 20 b to return from the released position B2 to the initial position B1.

In this embodiment, the pushing portion 25 b of the button 20 b is enabled to push the stylus 2 out of the accommodation recess 21 b by pressing the first operation portion 29 b and the second operation portion 30 b of the button 20 b. Thus, compared to a conventional approach of picking the stylus 2 by a finger, the design of operating the button 20 b to withdraw the stylus 2 from the accommodation recess 21 b provides a more convenient stylus pick-up operation. In particular, even when a user wears gloves, the user is still able to easily press the button 20 b to push the stylus 2 out of the accommodation recess 21 b and then directly take the stylus 2.

Moreover, the stylus 2 is pushed out of the accommodation recess 21 b by the pushing portion 25 b of the button 20 b, in a direction perpendicular to the longitudinal axis P2 of the accommodation recess 21 b, but not in a direction of the longitudinal axis P2 of the accommodation recess 21 b. Thus, it is not necessary for the accommodation recess 21 b to extend to the edge of the casing 10 b, hence minimizing the influence of a reduced internal space of the casing 10 b caused by the accommodation recess 21 b provided and further benefiting the utilization of the internal space of the casing 10 b.

Next, to place the stylus 2 back to the accommodation recess 21 b, in a state where the button 20 b is at the initial position A1, the stylus 2 is directly fitted into the accommodation recess 21 b of the button 20 b.

In this embodiment, when the button 20 b is not pressed, even if the casing 10 b receives an unexpected external impact (such as falling onto the ground), it is ensured that the stylus 2 located in the accommodation recess 21 b is still limited by the first stopping portion 27 b and the second stopping portion 28 b, and is kept in the accommodation recess 21 b.

In this embodiment, the number of the elastic members 41 b and 42 b is two; however, the present invention is not limited thereto. In another embodiment, the casing assembly may include only one elastic member. In yet another embodiment, the elastic member may be omitted from the casing assembly.

When the button 20 b is at the initial position B1, the pushing portion 25 b is not limited to being slightly protruding from the arc inner wall surface 22 b of the button 20 b. In another embodiment, when the button is at the initial position B1, one end of the pushing portion may be aligned with the arc inner surface of the button or be withdrawn into the arc inner surface of the button.

In this embodiment, the button 20 b has a through hole 24 b for the pushing portion 25 b to pass through; however, the present invention is not limited thereto. In another embodiment, the button may exclude such through hole. In such configuration, the pushing portion may be located next to one of the two opposite ends of the receiving portion of the button. When the button moves from the initial position to the released position, the pushing portion is still able to push the stylus out of the accommodation recess.

In this embodiment, the surface forming the accommodation recess 21 b is the arc inner wall surface 22 b; however, the present invention is not limited thereto. In another embodiment, the surface forming the accommodation recess may be a surface with angles and corners.

In this embodiment, the button 20 b includes two operation portions (the first operation portion 29 b and the second operation portion 30 b); however, the present invention is not limited thereto. In another embodiment, the button may include only one operation portion.

In the casing assembly according to the embodiments above, the pushing portion of the button is enabled to push the stylus out of the accommodation recess by operating the operation portion(s) of the button. Thus, compared to a conventional approach of picking the stylus by a finger, the design of operating the button to withdraw the stylus from the accommodation recess provides a more convenient stylus pick-up operation. In particular, even when a user wears gloves, the user is still able to easily press the button to push the stylus out of the accommodation recess and then directly take the stylus.

In addition, when the button is not pressed, even if the casing receives an unexpected external impact (such as falling onto the ground), it is ensured that the stylus located in the accommodation recess is still limited by the stopping portion(s), and is kept in the accommodation recess.

Moreover, the stylus is pushed out of the accommodation recess by the pushing portion of the button, in a direction perpendicular to the longitudinal axis of the accommodation recess, but not in a direction of the longitudinal axis of the accommodation recess. Thus, it is not necessary for the accommodation recess to extend to the edge of the casing, hence minimizing the influence of a reduced internal space of the casing caused by the accommodation recess provided and further benefiting the utilization of the internal space of the casing.

Although the present invention is disclosed by way of the preferred embodiments above, the embodiments are not to be construed as limitations to the present invention.
